To all whom it may concern Be it known that we, HARRY E. KAUP and RICHARD J lVILooX, citizens of the United States, residing in Bellevue and Carnegie, respectively, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Discharge-Door-Operating 'Mechanism, of which the following is a specification.

This invention relates to railway dump cars and particularly to that type of dump car in which thedischarge doors are supported and operated by a bodily movable shaft. Heretofore it has been found that, in dump cars of the above type in which the discharge doors do not extend to the end of the car and have the discharge door operating shaft extended some distance beyond the end door of the car, the' shaft, when it is being operated to open or close the doors, will not move parallel with the longitudinal center line of the car and will thus cause the" shaft and associated parts to become inoperative. q

An object of the present invention isto provide means whereby a bodily movable discharge door operating shaft that extends some distance beyond'the end door of a car, is caused to move parallel with the longitudinal center line of the'car as the shaft is being operated to open or close thedischarge doors. i V

, This :and'other objects will be apparent from the following description.

Referring to the drawings in whichlik'e reference characters referto like parts, F igure 1, is a plan view of a portion of a car embodying the invention: Fig. 2, is a side elevational view of the same; Fig. 3, is a cross sectional view of a portion of the car taken on the line 3 3 of Fig. 1; Fig. l, is an enlarged detail longitudinal sectional view taken on the line 4:ft of F ig. 1 and 'Fig. 5, is an enlarged detail cross sectional view taken on the line 5-5 'of Fig. 2.

There are var ous types of cars, to which the hereinafter described mechanism may be applied. some of which are illustrated in 1 Patent No." 791,348, granted May "30,1905, [to Charles A. Lindstrom and John F. S'treib. For illustrative purposes, a car of 'thehopper type has been shown in the drawings, which has an underframe comprising a center silll, end sill 2, bolsters 3 Specification of Letters Patent.

and intermediate.transverse members 4:, all of which may be of anydesired-construe tion and suitably connected together. The body of the car comprises sloping end'fioors 5 and-side walls 6 which floors and walls are suitably connected with-the underframe and with each other. The lower edge portions of the sidewalls and: sloping floors together with the center sill and transverse members 4, define discharge openings on both sides of the longitudinal center 11116 mounted in slots formed in members 1O which are preferably secured to the end sill 2, bolsters 3 and transverse members, 4;"0f

the underframe. To each of these shafts are preferably secured a plurality of.v spirally grooved drums 11, to each of which one end of a chain 12 is connected, the other end of the chain being connected with the outer or free edge of the door preferably through the medium of a member 13' which is se cured to the door. This member 13 is provided with a serrated shoe portion 14 which is adapted to engage with a serrated roller 15 securedto'the shaft, which roller may be made integral with the spirally grooved drum 11.

- Each of the shafts9 extend a considerable distance beyond the end-door 7 and a sufficient' distance beyond the support for the end portion of the shaft to apply a lever or other suitable operating device. Intermediate the support for the end portion ofthe shaft and the end door 7, the shaft is provided with a serrated or toothed member .16 which is adapted to engage with a, serrated or toothed member 17 secured to the underside of the platform 8 and located preferably above the shaft, which members,

when in suchengagement and the shaft is rotated, cooperate to move. said shaft bodily '111 directions transversely of the car.

termediate the support for the'end portion of the shaft and the end door 7 and preferably near the members 16 and 17, a chain 18 or any other suitable connection is provided one end of which is attached to the shaft and the other end to a member 19 secured to the underside of the platform '8. When the shaft is being rotated in the door closing direction this chain 18 will wind upon the shaft and will assist in causing said shaft to move out of notches 20 formed in the bearing members 10.

Assuming the discharge doors to be in their closed positions and it is desired to open them, the operations are as follows: the operator, by the use of a suitable lever or device .rotates the shaft 9 in the direction as indicated by the arrows in Figs. 3 and 5 which causes the serrated shoe portions 1% and rollers 15 and the members 1.6 and 17 to cooperate to move the shaft outwardly a sufficient distance as to be substantially free of the doors, at which time the shaft drops into the notches 20 and the doors are per mitted to open by gravity, the shaft rotating freely in so. h notches as the doors move to open positions. It will be noted that as the shaft moves into the notches 20 the member 16 moves out of engagement with the member 17 to a position as shown in dot and dash line's in Fig. 5, and will thus permit the shaft to rotate freely in the notches 20. To close the doors the operator rotates the shaft 9 in a direction opposite to that indicated by the. arrows in Figs. 3 and 5 which causes the chains 12 to wind upon the drums 11 and the chain 18 to wind upon the shaft until such time as the chains 12 have raised the doors to such a position that the outer end portion of the serrated shoe 1% is slightly above the serrated portion of the rollers 15 at which time a continued rotation of the shaft and the winding of the chain thereon creates tension on the chains 12 and 18 and causes the shaft to move bodily out of the notches 20. As the shaft moves out of the notches 20 the rollers 15 will engage with the shoe portions 1 and the member 16 will engage with the member 17 and a continued rotation of the shaft will cause said rollers and shoes and the members 16 and 17 to cooperate and cause said shaft to move inwardly a sufiicient distance to close the doors and to support them in closed positions.

It will be apparent to those skilled in the art to which this invention appertains that many changes may be made in the details and arrangement of the parts forming the invention without departing from the spirit and scope of the appended claims.
